Cusco 404477A Type I & II Lower Arm Bar Chassis Brace

The Cusco 404477A Lower Arm Bar is a precision-engineered chassis brace designed to improve body rigidity, steering response, and overall handling performance. Constructed from tubular high-tension lightweight aluminum and finished in an anti-corrosive paint coating, this bar is built to withstand the elements while minimizing unsprung weight.

Cusco offers this lower arm bar in two configurations to suit different performance needs:

Type I – 2-Point Lower Arm Bar:

• Connects the lower arm points at two locations to reduce chassis flex
• Improves steering rigidity and response during cornering
• Lightweight tubular aluminum construction with anti-corrosion coating
• Bolt-on installation using standard hand tools — no cutting or welding required
• Includes all necessary hardware for installation

Type II – Multi-Point Lower Arm Bar:

• Connects lower arm mounts at multiple positions for greater rigidity than the Type I
• Maintains body rigidity under extreme cornering loads
• Significantly improves steering response and traction
• Same durable tubular aluminum construction and anti-corrosion finish as Type I
• Bolt-on installation using standard hand tools — no cutting or welding required
• Includes all necessary hardware for installation

Whether you choose the Type I or Type II configuration, the Cusco Lower Arm Bar is a proven chassis reinforcement solution trusted by performance enthusiasts and motorsport competitors worldwide. Both versions reduce body flex to deliver sharper turn-in, more predictable handling, and improved driver confidence on the street or track.
